Photoshop CS4 for Photographers is an essential course for any digital photographer who wants to master the software's vast array of image enhancement techniques. Professional photographer and instructor Chris Orwig uses his own compelling images to demonstrate how the power of Photoshop can make photographers more passionate about their work. He covers many aspects of the application, such as working with RAW images, using curves and levels, making images snap, and enhancing bland photographs by converting them to black and white. Exercise files accompany this course.
In this movie, we are going to continue to work with the same image. Now we are going to sharpen this image so that we can send it via email or post it online. We go to the Background layer, right- click or Ctrl-click and choose Convert To Smart Object. Next we want to name that layer, and I'll go ahead and name this 'original'. Next we will navigate to the Filter pulldown menu and select Sharpen, and choose Smart Sharpen. Now you could use any of your sharpening techniques here, I'm just going to choose Smart Sharpen because I have to choose one and because it is a pretty good sharpening technique. I'll turn More Accurate off, and here is what I want to do. Advanced is on, Remove, Lens Blur, Amount, somewhere in the high one hundreds, right. Your Radius, either 0.1 or 0.2, sometimes 0.3, although typically it's best to have a real low radius. And then to dial in the sharpening with the Amount here, and we go ahead and find the sweet spot with the sharpening.
Now keep this in mind. One of the things that I'm going to do when I'm sharpening for the web is over sharpen, I hate to say that. What happens is when you save for web, you actually are throwing away pixels. So your edge definition isn't going to be as strong, your areas of sharpness are not going to be as sharp. So we are just going to barely over sharpen, just a little bit, so that then when we save for web, it kind of subtlest back into this nice, nice view. So I click on the image before and after, it should be subtle sharpening, yet it should feel like it's just a little bit not much. Well I think that looks pretty good, I'll click OK to apply that.
Now the next thing that I need to do, is to change the blend mode of the sharpening there. So I'll double-click on the icon here, which will open up my blending Options, and I'm going to take this to a blend mode of Luminosity. Now that's the same thing as sharpening on a new layer and changing that new layer blend mode to luminosity, so we are just sharpening the luminous values, we are not exaggerating any noise. Like that it looks good, click OK to apply that and then be sure to look at your before and after. Make sure your image is looking better and we will zoom in on this one so that you can see some of the subtle details here.
Here is our before and then after, and zoom in even further just to illustrate, hey I'm sharpening it, there is my before, there is my after, it is subtle yet significant, it's a little bit over sharpened but just barely, just barely. All right, well now as the image is sharp, we need to work on its color and tone. We will do that in the next movie.
